Rhy mitigates inflammation in asthmatic mice. Asthma models were established by OVA challenge and treated with 40 or 80 mg/kg Rhy. (a) The histopathological changes in lung tissues from each group were assessed by HE staining. Bar = 200 μm. (b) Inflammation scores in each group. (c-e) The levels of IgE in serum, IL-6 and IL-13 in bronchoalveolar lavage fluid were detected by ELISA. N = 6 for each group. The results were presented as mean ± SD. * p < 0.05, ** p < 0.01, *** p < 0.001. OVA, ovalbumin; Rhy, rhynchophylline; HE, hematoxylin-eosin; IL, interleukin; ELISA, enzyme-linked immunosorbent assay; SD, standard deviation
